Crystals Procurement Notes

Verify the specific ordering suffix to ensure the correct load capacitance and frequency tolerance match system requirements. Confirm that the 4-SOJ package dimensions align with PCB footprint specifications. Check for RoHS compliance documentation if required by regulatory standards. Ensure storage conditions adhere to manufacturer guidelines to maintain frequency stability over time.

Crystals Selection Notes

Select this component when a precise 4.9152 MHz reference is required for surface-mount assembly. The 20 pF load capacitance must be compatible with the host circuit's capacitive loading. Consider the 150 Ohm ESR limit to ensure adequate drive level margins. The ±50 ppm stability suits applications not requiring high-precision temperature compensation.

Crystals Part Context

This part belongs to the SXT144 series of MHz crystals from Suntsu Electronics. The series offers various frequencies and packages for general timing needs. The SXT14420AA17 variant specifically denotes the 4.9152 MHz frequency with standard commercial-grade stability parameters suitable for consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include other 4.9152 MHz crystals in 4-SOJ packages with matching 20 pF load capacitance and similar ESR values. Verify pin compatibility and electrical characteristics before substitution.
